Definitions
- the invention relates to a plate-like Water aerator, especially for water treatment or at Drain, with a rigid, essentially flat Bracket and one arranged thereon to exit the Air-finely slotted plate made of an elastomer, whereby the bracket one or more of the plate covered, trained to supply air Connectors and one vertically down angled, circumferential edge of a essentially U-shaped edge part of the plate is enclosed.
- a plate-like Water aerator is for example in the patent US 5,693,265.
- the invention is based, which Edge fastening to train their reliability and Life can be increased.
- the aerator which is preferably circular in plan, is made by fed from below via a nozzle 1; he is firmer Part of a rigid holder with base body 2, one angled vertically downwards, has peripheral edge 3. Runs parallel to edge 3 - also directed vertically downwards - one circumferential rib 5, which is however longer than the edge 3 (Length measured from the base body 2).
- the wall thicknesses the rib 5 and the edge 3 are substantially the same large, their mutual distance 6 corresponds approximately to that Wall thickness of the edge 3. This creates between the edge 3 and the rib 5 a circumferential groove 7.
- Loose on the base body 2 is one with fine Slotted rubber plate 8, which is suitable for the discharge of fine air bubbles if biased air in the nozzle 1 and thus between Plate 8 and base body 2 is passed.
- the legs 10 and 11th enclose the margin 3 between them. Furthermore, the upward free leg 10 the circumferential groove 7 free of play.
- the leg 10 To mount the plate 8, the leg 10 to a certain extent can be rolled into the circumferential groove 7. in the In the event of disassembly, sharp tools must also be used be used to remove the leg 10 from the circumferential groove 7 to be able to bring out what is only overcoming anyway of vacuum forces is possible. Hence for the Operation of permanent, firm anchoring of the edges of the Plate 8.
